When offset parameter is 0 replace tvb_bytes_exist() with the faster tvb_length().
On the other hand
if (tvb_bytes_exist(tvb, 0, 20)
is more readable than
if (tvb_length(tvb) >= 20
so only do it in heuristic function

This is a new dissector for STUN v2, that is currently in WGLC at the IETF.
- Keep packet-stun.c for the RFC 3498 protocol, plus the STUN and TURN
drafts up to draft-ietf-behave-rfc3489bis-02 and
draft-rosenberg-midcom-turn-08, as there is some huge deployments using
this. There will be no modification to this dissectors in the future,
excepted perhaps to add support for retransmission or things like this.
- Add a new dissector packet-stun2.c for the new STUN (currently in
WGLC), the STUN relay-usage (formerly known as TURN) and the other
usages that will be added in the future (IPv6, NAT Behavior, etc...).
